I am working on a drawing application based on GLPaint code. Do somebody know how to get an effect like this ? I have tried with different values for the width and the Height for the brush, but still it remains same .
Do i need to consider glBlendFunc() ? or Is it achievable thorough changing the width and the heigh of the brush.
Thanks in advance.
The easiest way to achieve that type of effect is to reducing the alpha from 1.0 to 0.7.
